Brands can document why specific influencers are chosen through a process involving several key steps:

1. Defining Campaign Objectives: Brands outline clear and precise goals for the campaign, such as increasing brand awareness, promoting new product lines, or boosting sales. This clarification helps guide influencer selection for alignment with objectives.

2. Audience Demographics: Brands target influencers whose followers match their desired audience demographics such as age, gender, geographic locations, interests, etc. Platforms like Flinque come handy here, providing detailed audience analytics.

3. Relevance: Brands check the relevancy between the influencer’s niche and their products or services. The influencer’s previous posts and engagements often provide these insights.

4. Authenticity: Brands favor influencers who communicate genuinely and have a passionate follower base. This connection between influencer and follower generates higher engagement and conversion rates.

5. Past Performance: Brands review the influencer’s historical data like engagement rates, reach, ROI, etc. Platforms like Flinque offer performance tracking functionalities which streamline this process.

6. Communication and Ethical Fit: Brands consider the communication style, transparency, and ethical fit of influencers – particularly in line with their corporate social responsibility (CSR) policies.

This selection rationale ensures brands work with influencers who are beneficial to their campaigns. By documenting this, the justification for choice becomes transparent, measurable, and accountable.

Comparatively, different influencer marketing platforms offer varying features to document the selection process. For example, Traackr features a built-in CRM for influencer relationship management while Flinque offers strong analytics features, all of which allows better campaign planning and performance tracking. Suitability, however, will vary on each team’s specific needs and objectives.
